Convert FLX to BVH

Understanding FLX and BVH file formats

FLX files are typically associated with animation data, often used in specific 3D animation or motion capture software. The format is not as widely adopted as others and may be proprietary, depending on the originating application.

BVH (Biovision Hierarchy) is a popular file format for storing motion capture data. It contains both the skeleton hierarchy and the motion data, making it a standard for transferring animation between 3D applications and game engines.

Why convert FLX to BVH?

Converting FLX to BVH allows you to use motion capture or animation data from specialized or legacy systems in modern 3D software such as Blender, Maya, or Unity, which natively support BVH files.

How to convert FLX to BVH

There is no direct, universal converter for FLX to BVH due to the proprietary nature of FLX files. However, you can follow these general steps:

1. Import the FLX file into the original software that created it (for example, Kaydara Filmbox or a similar animation tool).
2. Export the animation to a more common format, such as FBX or directly to BVH if supported. Use the menu: File → Export → BVH or File → Export → FBX.
3. If only FBX export is available, use a 3D tool like Blender to import the FBX file and then export it as BVH: File → Import → FBX, then File → Export → Motion Capture (.bvh).

Recommended software for FLX to BVH conversion

• Blender: Free and open-source, supports FBX and BVH formats. Ideal for intermediate conversion.
• Autodesk MotionBuilder: Professional tool for motion capture data, supports a wide range of formats including FLX and BVH.
• Online-convert.com: For direct format conversions if you have an intermediate format like FBX.

Tips and considerations

• Always check the skeleton hierarchy after conversion to ensure correct mapping.
• Some data may be lost or require manual adjustment due to differences in format capabilities.
• If you encounter issues, consult the documentation of the original software or seek community support for custom scripts or plugins.
